Abstract (en)
[origin: EP1101692A2] The operating device has at least one double-action working cylinder (1) with cavities (2, 3) each connected by a no-return valve (7, 8) to a switchable pressure supply (6). Each cavity is connected via a pressure limiting pre-tension valve (10, 11) to a pressure reservoir (12). At least one cavity is also connected via at least one further pre-tension valve (14, 15) to the reservoir. The valve is connected via a control line (16, 17) to the pressure supply.
